The first embodiment is as follows:
a lens blank softening holder comprising:
the transmission mechanism comprises a driving gear 11, a driven gear 12 and a transmission belt 13, wherein the driving gear 11 and the driven gear 12 are symmetrically arranged on the inner sides of two ends of the transmission belt 13;
the device comprises a base block 2, wherein a connecting seat 21 is arranged above the base block 2, and the side edge of the base block 2 is connected with the side edge of a transmission belt 13;
and the fixing frame 3 is adjustably connected to the connecting seat 21.
Specifically, different from the layered injection molding technology of the lens in the prior art, a thick-wall injection molding lens is formed by multiple times of injection molding from inside to outside layer by layer, and in order to realize one-step molding of the lens, after the lens blank is formed by injection molding, the lens blank is heated and softened and then placed into a pressing mold for pressing and molding.
In the heating and softening process of the lens blank, the lens blank is suspended in a heating furnace through the support, a heating mechanism of the heating furnace is positioned on the side edge of a fixed frame 3, an operator suspends the lens blank onto the fixed frame 3 from the end part of a transmission belt 13, a driving gear 11 drives a transmission belt 13 to move, a driven gear 12 enables the transmission belt 13 to keep tension, the transmission belt 13 drives base blocks 2 which are uniformly distributed and connected to the side surface, so that the fixed frame 3 and the lens blank move along the track of the transmission belt 13 together, the lens blank is fully heated in the heating furnace, when the lens blank returns to the initial position again, namely heating and softening are completed, the operator can take away the lens blank to perform the next step; the transmission belt 13 is connected with a plurality of base blocks 2 which are uniformly distributed, so that a plurality of lens blanks can be heated and softened at the same time, and the production efficiency is improved; the orientation of mount 3 can be adjusted to adjustable connection between mount 3 and connecting seat 21, makes things convenient for not unidimensional lens material embryo to hang, also can change not unidimensional mount 3.
